Christine Kendrick, PhD City of Portland

Air Sensors International Conference

Why air quality sensors?

• Respond to community concerns

• Could sensors be used to:

• Perform before and after assessments?

• Compare neighborhoods?

City of Portland’s Approach

• Technical and sustainability considerations:

• Sensor limitations

• Electronics waste minimization

• Co-located study design

• Sensor review

• Multi-Vendor Sensor Deployment

Need to overestimate costs of maintenance

Increase FTE for data analysis, integration, maintenance scheduling

Methods to evaluate local effects when you have limited reference data

Integration across sensor devices

Integration across sensor deployments

Best Practices So Far

• Consider sustainability of sensors themselves

• Plan for maintenance and management costs

• Re-visit your original question often to identify what type of data you need to take action
